Indoor Trapezium Window Seat Cushions

Bay windows commonly angle outward from the wall, giving the seat beneath them a wider front edge than back edge, which a standard rectangular cushion won't follow. Entering your own four measurements lets you create a cushion that follows the actual angle of your bay rather than settling for an approximate fit.

Choose from our range of indoor fabrics and add piping for a tailored finish that highlights the angled shape.

A reading nook built into an angled alcove or bay needs a cushion that follows the splay of the walls rather than sitting square across it. Custom dimensions let you match the depth and angle of your nook, so the cushion sits flush without gaps at the back.

Select comfort-plus foam for a softer feel in a spot you'll curl up in often, and add ties or sewn Velcro to help keep the cushion in place.

Built-in dining nooks that follow an angled bay or splayed wall need a cushion shaped to match, rather than a straight-edged one that leaves gaps at the corners. A trapezium cushion made to your own measurements follows the actual angle of your banquette.

Select commercial-grade foam for banquette seating that sees daily use, or choose comfort-plus foam for a softer feel in a family dining nook.

A trapezium window seat cushion suits window seats with angled sides, such as bay windows. If your window seat has straight front and back edges instead, our indoor rectangular window seat cushion is designed to follow that straight-edged shape. If your window seat wraps around a corner where two walls meet, our left or right mitred window seat cushion is designed to follow that corner.

Check the shape of your window seat before ordering, and enter your measurements above to create a window seat cushion made specifically for your furniture.
